' trolley wheel whereby the active life of the to provide duplicate wireengaging surfaces,

each surface constituting one-half .of the wire groove of the completewheel, whereby the Sections may be connected to utilize either of theirrespective wire engaging surfaces'to form the wire groove.

The invention will be described in the following specification,reference being had particularly to the accompanying drawings, in whichFigure 1 is a sectional view taken on a plane extending verticallythrough a trolley wheel constructed in accordance with our invention,and Fig. 2 is a detail perspective view of one 6f the sections of thetrolley wheel.

Referring particularly to the accompanying drawings, wherein is shownthe preferred details of the present invention, 1 represents a trolleyharp from the head plate 2 of which projects, in diametrically opposedrelation harp arms 3. The arms 3, which are of an appropriate length,are formed at their upper or terminal ends with bearings a to receivethe shaft 5 of a trol- The sections are adapted to be secured in'wheel-forming position by a series of bolts 12, appropriately securedinplace to avoid projection, the use of the bolts securing the sections soas to arrange their adjacent wire engaging surfaces to form a trolleywire groove centrally of the wheel.

It will be understood that if desired the bolts 12 may be dispensed withwithout interfering in any degree with the proper function of thesections, as the bushing 7 operates to hold the sections in contact, andtheir freedom for independent movement when the bolts are not used doesnot interfere in any degree with their function or result. As eachsection 8 and 9 has duplicate opposing wire engaging surfaces 10 and 11,it is obvious said sections may be secured together to arrange theirsurfaces 10 to form the groove, or to arrange their surfaces 11 ingroove-forming position. It is .at once obvious, therefore, that withthe wire engaging surfaces, as 10, rendered imperfect by use, a reversalof the sections to arrange their surfaces 11 in groove-forrningposition, will provide a new and perfect groove. The life of the trolleywheelis thus doubled, without requiring the removal or addition of anyparts.

Having thus described the is claimed as new, is i '1. A trolley wheelcomprising sections each having its peripheral edge shaped to provide aplurality of independent wire engaging surfaces, any two of the wireengaging surfaces forming a wire receiving groove when the sections areassembled in wheel forming position, and means securing the sections inwheel forming position against relative movements. 0
